South Africans, Paul and Andrea, are lovers living in France. Paul is fiftyish and white; Andrea is thirty and “coloured.” He has just asked her to marry him. She travels to Provence ostensibly to research sites for a film to be based on Paul’s endlessly forthcoming novel about fourteenth-century plague. But the real reason for the journey is to test her feelings about his proposal—she is leaning to ‘yes.’

As five days roll by, she relives the trajectory of her life: her impoverished parents, her thwarted education, her angry, imprisoned brother, and the previous affair with Brian, a British historian with whom she was captured ‘in flagrante,’ sent to trial, found guilty, and offered prison or voluntary exile. Brian and Andrea left South Africa together, but their relationship eventually crumbled. She had trouble understanding his passion for the past and his love of detail.

In Provence, Andrea avoids places that Paul had wanted her to go, finding strength in solitude and independence. But that feeling is shattered when he asks her to rescue their penniless, black friend, Mandla, an anti-apartheid activist who has been betrayed by a comrade who turned out to be a spy.

Andrea doesn’t like Mandla, his sanctimonious accusations, arrogance, and probing. He is a racist and a male chauvinist, given to violence. But his constant questioning finally unleashes deeper memories of the shocking abuses of her life in apartheid South Africa—memories she has suppressed or attempted to blame on class struggle rather than racial intolerance. She tries to provoke his empathy with the terrible tragedy of the long ago plague. He resists, being concerned far more with the present, but he relents a little and begins to see racism as a plague and walls as feeble, futile attempts to exclude others.

Andrea falls for Mandla, makes love with him near the plague wall, and decides to refuse Paul and return to South Africa. But Mandla rejects a future with her because he wants no vulnerability in his struggle. He is killed in the night by a car. Was the death deliberate? accidental? suicide? Andrea leaves anyway.

In a short second part, Paul writes to Andrea of his own growing doubts about their future together despite his love.
